  5. Discard virus infected plants.
  6. Disinfest tools used for vegetative propagation frequently.

Can cucumber mosaic virus spread to other plants?

Cucumber mosaic virus can infect plants from over forty families, including vegetable crops like tomato, lettuce and spinach, flower crops like gladiolus, petunias, impatiens and rudbekia, and a wide variety of weeds. All of the mosaic viruses can also infect weeds in the cucurbit family.
